Finite Strip Analysis for Thin-walled Members

Computer Program and Design Specification

Thin-walled members, by their very nature, have the potential to suffer from a variety of cross-section stability problems. CUFSM employs the semi-analytical finite strip method to provide solutions for the cross-section stability of such members. The software has been successfully used by researchers, educators, students, and practicing engineers. While CUFSM is most commonly used for thin-walled cold-formed steel members, it has also been used for a large variety of other materials and applications.


Design of Cold-Formed Steel Members Using the Direct Strength Method

As approved July 2003 by the American Iron and Steel Institute Committee on Specifications and finalized January 2004. App. 1 of the North American Spec. for the Design of Cold-Formed Steel Structural Members:
Specification January 2004 version
Commentary January 2004 version

Note, improvements continue to be made and are now continually made available in future editions of the North American Specification. Currently AISI-S100-07 contains the latest Specification approved procedures for the Direct Strength Method. In 2010 a DSM method for inelastic bending reserve was approved.
